Abstract: A mower having a locking mechanism for locking a moveable handlebar of the mower in its operating position is provided. The mower further includes an actuator for controlling operation of the mower so as to permit or not permit operation of an implement powered thereby when the handlebar is in its operating position. Additionally, the locking mechanism may be used to assist in the fastening of an attachment such as a debris collection receptacle. Also, since the handlebar may be moved into a non-operating position, the handlebar may be used as a prop so as to, for example, permit necessary maintenance on the underside of the mower to be more easily accomplished.

Abstract: A fill level indicator (7) for a tank (6) of an internal combustion engine (5) has a housing (8) with an inner chamber (9) connected to the tank (6) to allow the fill level indicator (7) to be visible. The housing (8) includes an upwardly directed housing strip (21) which projects laterally from an outer face (20) of the housing (8). The housing strip (21), when in a fitted condition, engages a groove (19) of an edge (16) to an upwardly directed opening (24) which is closed by a cover (14) which may be fixed to the housing (8). The cover (14) includes at least one lug (28) which is tensionable against the tank edge (16) and the cover (14) extends over an upper end (13) of the housing (8). A labyrinth seal is provided between the housing (8) and the cover (14), and the seal forms connecting ventilation channels (25, 26, 27), arranged one above the other.
